DIE FOR COLLAR PRESSING MACHINES Filed Feb. 27, 1941 lul- Fig.5 a FIGB STEPHEN STA 00B INVENTOR.

BY f m l'wfl ATTORNEY Patented Oct. 21, 1941 UNITED STATES PATENT OFFICE 2,259,865 DIE FOR COLLAR PRESSING MACHINES Stephen Stadub, Brooklyn, NY. Application February 27, 1941, Serial No. 380,777 9 Claims. (01. 22s-2) 7 My invention relates to dies for collar pressing machines and has particular reference to dies used in machines for pressing and shaping shirt collars.

In my United States Patents Nos. 2,141,051 and 2,222,447, I disclosed dies having collar supporting blocks with side walls extending above the block, the walls described in the Patent No. 2,222,447, being movable for pressing against the edges of a collar placed on the die block. I have found, however, that such a construction has a disadvantage in that it is difficult to maintain the edges of the die block and the side walls clean from particles of starch, lint, etc., which adhere to the surfaces from the collars.

My invention has for its object, therefore, to provide a die having a lower die block without any side walls, so that its surface can be easily kept clean. For pressing the edges of the collar I provide cylindrical members movably supported at the sides of the upper die block, the cylindrical members being pressed against the edges of the collar only when the upper block is lowered. The curvature of the cylindrical members facilitates their movement against the edges of the lower block.

Another object of my invention is to provide means to press the cylindrical members against the edges of the collar when the upper block is lowered. and placed against the lower block. This is accomplished in my device by springs at the sides of the lower block, the springs engaging the lowered cylindrical members and pushing them against the edges of the lower block.

Still another object of my invention is to facilitate cleaning of the cylindrical members. I mount them for this purpose on shafts, so that the cylindrical members will present different portions of their surface to the edges of the collar and can be used for a long time without cleaning.

My invention is more fully described in the accompanying specification and drawing, in which:

Fig. 1 is a front view of my die with the upper block in a raised position partly in section;

Fig. 2 is a similar view with the upper block lowered;

Fig. 3 is a top plan view;

Figs. 4 and 5 are enlarged detail views of the die with the side rollers;

Fig. 6 is a bottom view of a modified die;

Fig. '7 is a detail view of another modification.

My collar pressing die consists of a base plate I' supporting a lower die block 2 with an electric heater 3 inside. The die block has sides converging at an angle corresponding to the angle of the point of a collar 5. The latter may be mounted on a thin fiat die plate 6 by means of a suitable mechanism, such as is described, for instance, in my foregoing Patent No. 2,141,051. An upper die block I is provided with side extensions 8 mounted on vertical rods 9. Springs l0, resting on the base plate I, support the upper block at an elevation above the lower block. The rods '9 are joined by a 'bar ll connected by a rod l2 with a pedal l3. The upper block is lowered by manually depressing the pedal.

For pressing and shaping the edges and point of the collar, rollers 14 are provided, rotatively mounted on rods or shafts [5 extending at the sides of the block. The inner ends of the shafts are pivoted on a pin IS, the outer ends being supported in brackets I! with elongated slots I8 permitting certain freedom of movement of the shafts in the plane of the block. Springs I9 are mounted on the base I and press on the rollers I4, when the upper block is lowered, the pressure of the springs causing the rollers to press against the edges of the collar.

The rollers converge at the converging end of the block, so that they can shape the collar to a fine point.

In order to enable the rollers to automatically adjust themselves to the shape of the collar, they are mounted on the shafts with a certain clearance, the holes 20 being of a larger diameter than the shafts l5.

A modified device is shown in Fig. 6, shafts 2| being mounted at both ends in brackets l1 and 22 with elongated slots.

Another modification is shown in Fig. 7, the rollers being replaced by curved members 23 pivoted on shafts 24 and engaged by springs IS. The rounded sides of the rollers l4 or members 23 facilitate their movement at the edges of the lower block. The rollers can be rotated so that new and clean surfaces can be presented to the collar edges. The lower block can be easily kept clean at all times, since it has no inside corners to gather dirt.

It is understood that my die for collar pressing machines may be further modified without departing from the spirit of the invention, as set forth in the appended claims.

I claim as my invention:

1. A die for collar pressing machines comprising a base plate, a lower die block on the plate having a fiat top and sides converging together at an angle corresponding to the angle of a shirt collar, an upper die block having a flat underside, means to support the upper block at an elevation above the lower block, means to move the upper block against the lower block for pressing a collar placed on the lower block, and members supported on side extensions of the upper block below its under side for pressing the edges of the collar.
